Summary:
Data has been migrated from Web TimeOff to Web TimeSheet. After the migration, the TimeOff calender in Web TimeSheet does not launch. Whenever, the TimeOff calender is clicked, it loads the 'List My Time Off Booking' screen and not the Calender as desired.

Solution:
This issue will occur if there were any rejected TimeOff in Web TimeOff application before the migration. Once migration is complete, the rejected TimeOff needs to be deleted and the web page need to be refreshed.This will resolve the issue i.e the TimeOff calender once clicked, will launch the calender and not the 'List My Time Off Bookings' screen.
